Given the calculation
[tex]2^3+3^3[/tex]The exponent index "3" indicates that the base number is being multiplied by itself 3 times, you can rewrite the calculation as follows:
[tex](2\cdot2\cdot2)+(3\cdot3\cdot3)[/tex]-Solve the multiplications from left to right, this is, multiply the first two numbers, and then multiply the result by the third one:
[tex]\begin{gathered} (4\cdot2)+(9\cdot3) \\ 8+27=35 \end{gathered}[/tex]The result of the given calculation is then:
[tex]2^2+3^2=8+27=35[/tex]
