Question

• Find the value of :
i) √(144)^-2
ii) (3)^-2


• Evaluate :
(3^2+4^2)^1/2​

Answer 1

Answer:

i). 6.9444 \times {10}^{ - 3}

ii). 5

Step-by-step explanation:

i)

$\sqrt{(144) {( - 2)}^{2} } = {144}^{( - 2) \times ( \frac{1}{2} } \\ {144}^{( - 1)} \\ \frac{1}{144} \\ 6.9444 \times {10}^{ - 3}$

ii)

${({3}^{2} + {4}^{2})}^{ \frac{1}{2} } \\ {(9 + 16)}^{ \frac{1}{2} } \\ {25}^{ \frac{1}{2} } \\ \sqrt{25} \\ 5$

Answer 2

Step-by-step explanation:

(√144)^-2=1/(√144)^2=1/144

(3)^-2=1/3^2=1/9

((3^2+4^2)&1/2=√(9+16)=√25=5
