70 = 1 : 71 = 7 ; 72 = 49 : 73 = 343 : 74 = 2401
The final digit repeats as the exponent increases by 4.
So 735 has the same final digit (3) as 73 : 760 has the same final digit (1) as 70.
They can be written as reciprocals with positive exponents. For example, 5-7 = (1/5)7
It is: 2*7 = 14 and no exponents are needed
It is: 7*17 = 119 and needs no exponents
5 x 7 = 35 No exponents required.
It is: 2*5*7 = 70 and no exponents are needed
Prime factorization of 98 using exponents: 2 * 7 * 7 = 2 * 7²
They can be written as reciprocals with positive exponents. For example, 5-7 = (1/5)7
1, 3, 7, 21 No exponents required.
3 * 7 * x No exponents necesary
It is: 2*7 = 14 and no exponents are needed
It is: 7*17 = 119 and needs no exponents
ANSWER: Prime factorization of 91 = 7 x 13
5 x 7 = 35 No exponents required.
It is: 2*5*7 = 70 and no exponents are needed
343 = 7 * 7 * 7 = 73
63 = 32*7
3 x 7 = 21 No exponents necessary.
