6. 7^5 • 7^6 = (1point)
a. 49^30
b. 7^30
c. 49^11***
d. 7^11

  1. Steve

    nope

    7^5 * 7^6 = 7^(5+6) = 7^11

    Better review the rules of exponents. The base does not change:

    a^m * a^n = a^(m+n)
    NOT
    (a^2)^(m+n)

  2. Steve

    7^5 * 7^6
    = 7*7*7*7*7 * 7*7*7*7*7*7
    = 7^11

    all 7's, no 49's
