Evaluate the expression.
Gemiola [76]

Answer:

98 is the answer of the expression

Step-by-step explanation:

AS it is a simple algebraic expression so these are solved by BDMAS rule which means that we have to solve the brackets first starting from the smaller bracket first which is inside a larger bracket then we will move to Division then multiplication then addition and then subtraction


so the following equation can be written as

= 2^{3}[\frac{1}{4}+4(36/12)]

First of all solving smallest bracket and division inside it

= 2^{3}[\frac{1}{4}+4(3)]

Multplying 4 inside

= 2^{3}[\frac{1}{4}+12]

Now solving the 2³

= 8[\frac{1}{4}+12]

Now solving the expression inside the bracket by taking LCM

= 8[\frac{1 + 4*12}{4}]

= 8[\frac{1 + 48}{4}]

= 8[\frac{49}{4}]

Now multiplying 8 with inside values

= [\frac{8*49}{4}]

AS 8 cuts out with 4 so

= 2 * 49

= 98

which is the answer of the expression
