The problem may start with:

pH= -log H+ = 4.82. The answer is 1.5x10 power -5. Again, Can you please show steps for maths.

4.82 = -log(H^+)

log(H^+) = -4.82

Take the antilog of both sides.

The antilog of log (H^+) is, or course, just (H^+). To find the antilog of -4.82, punch that number into your calculator and hit the 10^{x}button. It should return 1.51 x 10^{-5}
