Answer 1

Step-by-step explanation:

1/4+1/64+1/25

=64+64+64/64

=3

Answer 2

Step-by-step explanation:

Given:-

(1/2)^2 + (1/4)^3 + (1/5)^2

To find:-

Evaluate (1/2)^2 + (1/4)^3 + (1/5)^2

Solution:-

Given numerical expression is

(1/2)^2 + (1/4)^3 + (1/5)^2

=>(1^2/2^2) + (1^3/4^3) + (1^2/5^2)

Since (a/b)^m = a^m ×b^m

=>(1/4) + (1/64) +(1/25)

LCM of 4,64,25 is 1600

4= 2 × 2

64 = 2 × 2 × 2 × 2 × 2 × 2

25 = 5 × 5

LCM(4, 64, 25)

= 2 × 2 × 2 × 2 × 2 × 2 × 5 × 5

= 1600

LCM = 1600

=>[(400×1)+(25×1)+(64×1)]\1600

=>(500+25+64)/1600

=>589/1600

Answer:-

The value of the given problem is 589/1600

Used formula:-

• (a/b)^m = a^m ×b^m
