    when we multiply same bases we should `add` exponents \[\huge\rm x^m \times x^n=x^{m+n}\]

    \(\color{blue}{\text{Originally Posted by}}\) @Nnesha when we multiply same bases we should `add` exponents \[\huge\rm x^m \times x^n=x^{m+n}\] \(\color{blue}{\text{End of Quote}}\) ADD not multiply

    yes exponent is right but it wouldn't be 7 times 7 here is an example \[ \huge\rm a^2 \times a^2= a^{2+2}=a^{4}\]

    so \[\huge\rm 7^5 \times 7^3 =?\]
