Express 256 × 243 in exponential form. Options: A . &nbsp 2 8 × 3 5 B . &nbsp 2 7 × 3 4 C . &nbsp 2 6 × 3 3 D . &nbsp 2 2 × 3 2

Answer: Option A : A We can write: 256 = ( 2 × 2 × 2 × 2 × 2 × 2 × 2 × 2 ) = 2 8 243 = ( 3 × 3 × 3 × 3 × 3 ) = 3 5 ∴ 256 × 243 = 2 8 × 3 5

Express 256×243 in exponential form.

Question

Express $256 \times 243$ in exponential form.

Options:

A .

2^{8} \times 3^{5}

B .

2^{7} \times 3^{4}

C .

2^{6} \times 3^{3}

D .

2^{2} \times 3^{2}

Answer: Option A
:
A

We can write:
$256 = (2 \times 2 \times 2 \times 2 \times 2 \times 2 \times 2 \times 2) = 2^{8}$

$243 = (3 \times 3 \times 3 \times 3 \times 3) = 3^{5}$
$∴ 256 \times 243 = 2^{8} \times 3^{5}$
