Answer 1

Answer:

250 is the answer .

Step-by-step-Explaination :-

$\rm {8}^{ - 1 } \times {5}^{3} \div {2}^{ - 4}$

$\longmapsto\rm (\dfrac{1}{8})^{1} \times 5 \times 5 \times 5 \div (\dfrac{1}{2}) ^{4}$

$\rm \longmapsto \dfrac{1}{8}×5^3÷\dfrac{1}{16}$

$\rm \longmapsto \dfrac{1}{8}×125\times 16$

$\rm \longmapsto \: 125\times 2\rightarrow \bf 250.$

Answer 2

Given :- solve :- 8⁻¹ x 5³ ÷ 2⁻⁴ .

Answer :-

we know that,

• a^ (-m) = 1/a^m .

so,

→ 8⁻¹ x 5³ ÷ 2⁻⁴ .

→ 1/8¹ * 5³ ÷ 1/2⁴

→ 1/8 * 125 ÷ 1/16

→ 1/8 * 125/(1/16)

→ 1/8 * 125 * (16/1)

→ 1/8 * 2000

→ (1/8) * (250 * 8)

→ 250 (Ans.)
