(i) \(512 = 2 \times 2 \times 2 \times 2 \times 2 \times 2 \times 2 \times 2 \times 2 = 2^9\)
(ii) \(343 = 7 \times 7 \times 7 = 7^3\)
(iii) \(729 = 3 \times 3 \times 3 \times 3 \times 3 \times 3 = 3^6\)
(iv) \(3125 = 5 \times 5 \times 5 \times 5 \times 5 = 5^5\)
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
