243 = 27 x 9 so perimeter is 2 x 36 ie 72.
3 3^5 = 243 (3 x 3) x (3 x 3) x 3 = 243 9 x 9 x 3 = 243 81 x 3 = 243
Let the length be 3x and the width be x: 3x*x = 243 3x2 = 243 Divide both sides by 3: x2 = 81 Square root both sides: x = 9 Therefore: length = 27 cm and width = 9 cm
They are powers of 3. 729 = 36 243 = 35 81 = 34 27 = 33 9 = 32 3 = 31
9x = 243 ln(9x) = ln(243) xln(9) = ln(243) x = ln(243)/ln(9) x = 2.5 NB this works with log10 too. NBB if you don't have a calculator, this kinda question will only have easy values of x like integer values or 0.5, so its always worth chucking numbers in.

1, 3, 9, 27, 81, 243, 729: (1 x 729, 3 x 243, 9 x 81, 27 x 27)
243, i had trouble with that question to! but its hard doing those numbers.27 multiplied by 9 is 243.
1 x 243, 3 x 81, 9 x 27.
1 x 243, 3 x 81, 9 x 27.
3 x 3 = 9 9 x 3 = 27 27 x 3 = 81 81 x 3 = 243 so: 3x3x3x3x3= 243
9 x 27 equals 243
The following equal 243: 27 x 9 81 x 3
