The angle between latitudes 30oS and 13oN is

If 9(x - 12 1 2 ) 3x2

Solve without using tables \( \log_{5}(62.5) - \log_{5}\left(\frac{1}{2}\right) \)

simplify 1√3−2 1 √ 3 − 2 - 1√3+2

change 7110 to base 8

Integrate 1−xx3 with respect to x

Evaluate \( \frac{3524}{0.05} \) correct to 3 significant figures

Solve for y in the equation 101 x 5(2x - 2) x 4(y - 1) = 1

If 2log3 y + log3 x2 = 4, then y is
