Answer 1

Step-by-step explanation:

Solve only 1st part else part you can try..

(4)^0= 1

(4)^-1=1/4

(2)^2=4

solve this equation:

(1+1/4)×4

(5/4)×4

5 Ans

Answer 2

Step-by-step explanation:

$( {4}^{0} + {4}^{ - 1} ) \times {2}^{2} \\ = (1 + \frac{1}{4} ) \times 4 \\ = \frac{4 + 1}{4} \times 4 \\ = \frac{5}{4} \times 4 \\ = 5$

$( {3}^{ - 1} \times {9}^{ - 1} ) \div {3}^{ - 2} \\ = \frac{1}{3} \times \frac{1}{9} \div \frac{1}{ {3}^{2} } \\ = \frac{1}{27} \times 9 \\ = \frac{1}{3}$

$( {11}^{ - 1} + {12}^{ - 1} + {13}^{ - 1} ) {}^{0} \\ = ( \frac{1}{11} + \frac{1}{12} + \frac{1}{13} ) {}^{0} \\ = ( \frac{156 + 143 + 131}{1716} ) {}^{0} \\ = ( \frac{430}{1716} ) {}^{0} \\ = 1$
