(i) \(6 \times 6 \times 6 \times 6 = 64\)
(ii) \(t \times t= t ^2\)
(iii) \(b \times b \times b \times b = b^ 4\)
(iv) \(5 \times 5 \times 7 \times 7 \times 7 = 5^2 \times 7^3\)
(v) \(2 \times 2 \times a \times a = 2^2 \times a ^2\)
(vi) \(a \times a \times a \times c \times c \times c \times c \times d = a^ 3 c ^4 d\)
Write equations for the following statements:
(i) The sum of numbers x and 4 is 9.
(ii) 2 subtracted from y is 8.
(iii) Ten times a is 70.
(iv) The number b divided by 5 gives 6.
(v) Three-fourth of t is 15.
(vi) Seven times m plus 7 gets you 77.
(vii) One-fourth of a number x minus 4 gives 4.
(viii) If you take away 6 from 6 times y, you get 60.
(ix) If you add 3 to one-third of z, you get 30
