Question

Evaluate 8‐¹× 5³ / 2-⁴​

Answer 1

Answer:

250

Step-by-step explanation:

8⁻¹ = 1/8

5³ = 125

2⁻⁴ is in the denominator so it can be taken in the numerator as 2⁴

We also know, 8 is 2³

So, we can cancel 2³ in 2⁴

We have with us now,

125 x 2 = 25 x 5 x 2

=250

Answer 2

Step-by-step explanation:

$\frac{ {8}^{ - 1} \times {5}^{3} }{ {2}^{ - 4} } \\ \frac{ - 8 \times 125}{ - 16} \\ \frac{ 1 \times 125}{2} = \frac{125}{2} \\ 62.5$
