Evaluate power (-3) to the 4th power

(-3)^4 = -3*-3*-3*-3

9 * 9

= 81

Just to add a note to Vinay's awesome answer, you want to be very careful with these two very similar things (especially if you're typing it in the calculator):

(-3)4 = 81

-(3)4 = -(34) = -(81) = -81

(-3)4 = 81

Hope this helps!

b) 1/3 * 1/5

step-by-step explanation:

each smallest part is 1/15 since the written one is 1/5 and it's divided by 3 equal parts. (1/5 )/3 = 1/15 = 1/3 * 1/5
