What is the perimeter of a rectangle with an area of 243 and a length that is 3 times the width?
243 = 27 x 9 so perimeter is 2 x 36 ie 72.
Fifth root of 243?
3 3^5 = 243 (3 x 3) x (3 x 3) x 3 = 243 9 x 9 x 3 = 243 81 x 3 = 243
The area of a rectangle is 243 cm2 The length is three times greater than the width What are the dimensions?
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
What is the pattern for 729 243 81 27?
They are powers of 3. 729 = 36 243 = 35 81 = 34 27 = 33 9 = 32 3 = 31
How do you solve 3 to the x power equals 243?
Notice that 243 is 3 to the 5th power.So your equation says:3x = 35I'd say that 'x' is probably 5.
