Mutiply the digits and add the powers and so (4*10^4)(2*10^5) = 8*10^9
(4*10)6 (40)6 4,096,000,000
42 = 4*4 = 16
Multiply (4) x (4) x (4) and get 64 .
You evaluate the power of the power first. For example, 4 to the power of (3 to the power of 2) is 4 to the power of 9 which is 262,144
4X10/10=4
(4*10)6 (40)6 4,096,000,000
Evaluate -6 to the power of 2
42 = 4*4 = 16
It is already in standard form.
32 4 plus 2 the third power -3 cannot be evaluate.
54
Multiply (4) x (4) x (4) and get 64 .
4^3 = 4*4*4 = 16*4 = 64
You evaluate the power of the power first. For example, 4 to the power of (3 to the power of 2) is 4 to the power of 9 which is 262,144
What is 1+2 with sum
4X10/10=4
4-2 = 1/42 = 1/16 = 0.0625
