...example, 54-f-52= (5 x 5 x 5 x 5) -5- (5 x 5 = 52. 828. A power of any number is raised to any other given power by multiplying its exponent by the exponent of the power to which it is to be raised. For example (42)2 (which means that 4 is to be raised to the second power,) = 42 x 45=44. OS iH CO... | |
