You're on a roll — here are the solutions to the math problems:
4) For 32, identify: a. the base number. b. the exponent.
- a. The base number is the number being multiplied by itself.
- Base number: 3
- b. The exponent is the number of times the base is multiplied by itself.
5) Colour all the square numbers on the multiplication board. What pattern do you see?
Square numbers are the result of multiplying a number by itself (n×n).
The square numbers on the multiplication board are:
1×1=1
2×2=4
3×3=9
4×4=16
5×5=25
6×6=36
7×7=49
8×8=64
9×9=81
10×10=100
These numbers form a diagonal pattern from the top-left corner to the bottom-right corner of the multiplication board.
6) Arrange these numbers in ascending order:
2,92,52,5,62,22,82,72,12,13,10,112,42,102
Step 1: Calculate the value of each number.
- 2=2
- 92=9×9=81
- 52=5×5=25
- 5=5
- 62=6×6=36
- 22=2×2=4
- 82=8×8=64
- 72=7×7=49
- 12=1×1=1
- 13=1×1×1=1
- 10=10
- 112=11×11=121
- 42=4×4=16
- 102=10×10=100
The list of values is: 2,81,25,5,36,4,64,49,1,1,10,121,16,100.
Step 2: Arrange the values in ascending order (smallest to largest).
1,1,2,4,5,10,16,25,36,49,64,81,100,121
Step 3: Write the original numbers in ascending order.
12,13,2,22,5,10,42,52,62,72,82,92,102,112
7) Arrange the above numbers in descending order:
To arrange in descending order, we take the ascending list and reverse it.
112,102,92,82,72,62,52,42,10,5,22,2,13,12
8) Fill in <,> or =
-
a. 22_2×2
- 22=4
- 2×2=4
- So, 4=4
- 22=2×2
-
b. 52_5×2
- 52=25
- 5×2=10
- So, 25>10
- 52>5×2
-
c. 92_9×9
- 92=81
- 9×9=81
- So, 81=81
- 92=9×9
-
d. 82_2×8
- 82=64
- 2×8=16
- So, 64>16
- 82>2×8
-
e. 112_10×11
- 112=121
- 10×11=110
- So, 121>110
- 112>10×11
-
f. 3×3_32
- 3×3=9
- 32=9
- So, 9=9
- 3×3=32
9) Numbers which have an exponent of 2 are called square numbers.
