7 cubed in index notation is expressed as ( 7^3 ). This means 7 is multiplied by itself three times, which can be calculated as ( 7 \times 7 \times 7 = 343 ).
7 cubed is equal to 343.
It is: 7 cubed = 343
In mathematical notation, a number cubed is written as x3. For 15 cubed, that would be 153 or (15 X 15 X 15 =) 3,375
15cubed or 153 = 3,3753,375 in exponential notation is 3.375 × 103
15 cubed = 15^3 or (3 x 10^3) + (3 x 10^2) + (7 x 10^1) + (5 x 10^0)
Ah, isn't that a happy little question! The factor of 28 in index notation is 2^2 * 7. See how we can break down 28 into its prime factors of 2 and 7, and then write it in index notation for a clear and beautiful representation.
23 x 7 = 56
Index notation for 125 = 1.25 × 102
7 cubed is equal to 343.
9.998 x 10 cubed
Use the definition of "cubed". 7 billion cubed is the same as 7 billion x 7 billion x 7 billion.
It is: 7 cubed = 343
In mathematical notation, a number cubed is written as x3. For 15 cubed, that would be 153 or (15 X 15 X 15 =) 3,375
12 cubed
15cubed or 153 = 3,3753,375 in exponential notation is 3.375 × 103
3 x 3 x 3 x 7 Or, if you want it in the index form, it would be 3 cubed (little three above the '3') x 7.
15 cubed = 15^3 or (3 x 10^3) + (3 x 10^2) + (7 x 10^1) + (5 x 10^0)
