Can someone please help me with this math question .

Alona [7]

No, Yes, No, Yes

using the laws of exponents

(1)

( $4^{3}$ )³ = $4^{9}$

4³ × 4³ = $4^{6}$

$4^{9}$ ≠ $4^{6}$ → No

(2)

( $3^{4}$ )^4 = $3^{16}$

$3^{8}$ × $3^{8}$ = $3^{16}$ → Yes

(3)

$18^{8}$ = (6 × 3 )^8 = $6^{8}$ × $3^{8}$ ≠ $6^{4}$ × $3^{4}$ → No

(4)

$20^{3}$ = (4 × 5 )³ = 4³ × 5³ → Yes
