what is b squared plus b squared
$$\\ \small{\text{I.$b^2+b^2=b^2(1+1)=b^2*2= 2*b^2$}}$\\$\small{\text{II.$b^2+b^2=b*(b+b)=b*(2*b)= 2*b^2$}}$$
b2= bxb
The answer???
Sorry but I don't know that. :/
$${{\mathtt{b}}}^{{\mathtt{2}}}{\mathtt{\,\times\,}}{{\mathtt{b}}}^{{\mathtt{2}}} = {{\mathtt{b}}}^{{\mathtt{4}}}$$
b^2+b^2=2b^2
b^2 + b^2= 2b^2
Now if it was b^2 * b^2 = b^(2+2) = b^4
Hope this helped.
