Question

Simplify [{(1/5) ^-3 - (1/3)^-2} ÷ (1/2) ^-3]. Please reply as fast as you can​

Answer 1

Answer:

14.50

Step-by-step explanation:

$(1 \div 5) {}^{ - 3} - (1 \div 3) {}^{ - 2}$

We will inverse it. By inversing it the the negative sqaure will be become positive like this

$(5)^{3} - (3)^{ 2}$

And it answer is 116

Then the next step is Getting the answer of {(1/2)^-3}

$(1 \div 2)^{ - 3}$

$(2)^{3} = 8$

last step is to divide the answer with 8

$116 \div 8 = 14.50$
