Compare the calculations of a2 and a x 2 for various values of a.

$$4 = 4$$

So, $2^2 \boxed{=} 2 \times 2$.

b)

$$25 > 10$$

So, $5^2 \boxed{>} 5 \times 2$.

c)

$$81 > 18$$

So, $9^2 \boxed{>} 9 \times 2$.

Classwork (10 April 2026)
Write the next three numbers in this cubic pattern: $1, 8, 27$
The pattern shows cubic numbers:
$1 = 1^3$
$8 = 2^3$
$27 = 3^3$
The next three numbers will be $4^3$, $5^3$, and $6^3$.

$$6^3 = 6 \times 6 \times 6 = 216$$

The next three numbers are $\boxed{64, 125, 216}$.

Homework (10 April 2026)

1. Calculate and fill in $<, >, =:$

a) $2^3 \boxed{?} 2 \times 3$

$$8 > 6$$

So, $2^3 \boxed{>} 2 \times 3$.

b) $1^3 \boxed{?} 1 \times 1 \times 1$

$$1 = 1$$

So, $1^3 \boxed{=} 1 \times 1 \times 1$.

c) $125 \boxed{?} 5^3$

$$125 = 125$$

So, $125 \boxed{=} 5^3$.

1. Calculate the cube roots:

a) $\sqrt[3]{27}$

$$3 \times 3 \times 3 = 27$$

So, $\sqrt[3]{27} = \boxed{3}$.

b) $\sqrt[3]{125}$

$$5 \times 5 \times 5 = 125$$

So, $\sqrt[3]{125} = \boxed{5}$.

Homework (13 April 2026) 2. Calculate the square roots:

a) $\sqrt{4}$

$$2 \times 2 = 4$$

So, $\sqrt{4} = \boxed{2}$.

b) $\sqrt{16}$

$$4 \times 4 = 16$$

So, $\sqrt{16} = \boxed{4}$.

c) $\sqrt{100}$

$$10 \times 10 = 100$$

So, $\sqrt{100} = \boxed{10}$.
