Question

plesae solve the above question

Answer 1

Answer:

7

Step-by-step explanation:

1/2^m * 2^(-m) = 1/4

2^(-2m)= 2^(-2)

therefore -2m=-2

m=1

Now, value of (4^m)½ + {5^(-m) }-¹

put m=1

(4)½+ (5-¹)-¹

2+5¹

=7

Answer 2

Answer:7

Step-by-step explanation:2^(-m)/2^(m)=1/4

1/(2^(m+m))=1/4

1/(2^(2m)=1/2^2

Comparing the equations, we get

m=1

So (4^m)^{1/2}+(1/5^m)^{-1}

Substituting the value,we get

(4^1)^{1/2}+(1/5^1)^{-1}

√4+5

2+5
