Use reciprocal and square tables to evaluate to 4 significant figures the expression $\frac{1}{24.56}$ + 4.362²

Use reciprocal and square tables to evaluate to 4 significant figures the expression
$\frac{1}{24.56}$ + 4.362²

Answers

(2.456 x 10^-1)^-1

= 0.407 x 10^-1 = 0.04072

4.362² = 19.027

0.0407 + 19.027

0.0407 + 19.027 = 19.06772

= 19.07 correct to 4 s.f
