Question

What is answer of this question[(-3/4)-2]2​

Answer 1

Answer:

5.5 or 2.2 (both will do)

Step-by-step explanation:

  [ ( $\frac{-3}{4}$ ) -2 ] 2

= [ $\frac{-3}{4}$ -2 ] 2    ( opening the small brackets )

= [ $\frac{-3}{4}$ - $\frac{2}{1}$ ] 2    (  any whole number's denominator is 1 by default )

= [ $\frac{-3-8}{4}$ ] 2     ( taking the LCM )

= [ $\frac{-11}{4}$ ] 2       ( solving the fraction )

= $\frac{-11}{4}$ × 2        ( opening the large brackets ) ( when there is no sign, it

                     becomes multiplication by default )

= $\frac{-11}{4}$ × $\frac{2}{1}$         ( any whole number's denominator is 1 by default )

= $\frac{-22}{4}$              ( denominator is multiplied by denominator and numerator is

                     multiplied with numerator )

At simplifying, we get 5.5 or 2.2

Answer 2

Given:  

$[(\frac{-3}{4}) -2]^{2}$

To find:  

To simplify the expression $[(\frac{-3}{4}) -2]^{2}$

Step-by-step explanation:  

• Here we need to simplify the expression $[(\frac{-3}{4}) -2]^{2}$
• We will use the BODMAS rule. We will first divide, multiply, add and subtract the expression.

Solution:

The LCM of 4 and 1 = 4

$[(\frac{-3}{4}) -2]^{2} \\\\ = [\frac{-3 -8 }{4}]^{2} \\\\\ [\frac{-11}{4}] ^{2} \\\\=\frac{-11}{4} *\frac{-11}{4} \\\\=\frac{22}{16}\\\\=\frac{11}{8}$

Hence. $\frac{11}{8}$ is the solution for $[(\frac{-3}{4}) -2]^{2}$
