The work will depend on how well you know your multiplication tables.
3^3 = 3*3*3 = 273^5 = 27*9 = 243
3^7 = 243*9 = 2187.

2 to the power of 7 minus 3 to the power of 3 divided by 7 is equal to 124 1/7 ≈ 124.14
7 and 75/100 = 7 and 3/4 = 31/4
343 is 7 to the power of 3 ( 7 x 7 x 7 = 343) To find 7 to the 3 power to the 2/3 power you multiply the exponents and raise 7 to that power: 3 x 2/3 = 2 7^2 = 49
5-(-2)-3-2 5-(-2)=7 7-3-2 7-3=4 4-2=2 2
63 21,3 7,3,3 3 x 3 x 7 = 63
7 to the power of 3 is: 7 x 7 x 7 = 343 Another way to write it is: 7^3 = 343
They are: 7^3 = 343 and 3^3 = 27
Reflexivity is a property of equality, i.e., X = X is always true. Thus -7 raised to the power of 3 equals -7 raised to the power of 3 is true.
3 x 7 = 212 x 5 x 7 = 70Select the common factor.The GCF is 7.
8/7 to the power of -3 is 0.669921875
10 to power of -7 = 3
