(1.00 x 10^5)NM - (3.96 x 10^3) NM = ?

I think that since they're both NM don't you think that you can just subtract them?

96,040 NM whatever NM stands for, and I didn't factor in significant figures.

Isn't that nanometers..Dr.Bob?

I have no idea but nanometers is nm, not NM. I think NM is New Mexico.

XD

OK. Watch the significant figures.

Why are these algebraic expressions used and explain the logical error: Since a = b, then a2 = a * b Subtract b2 from both sides a2 – b2 = a * b – b2 Factor both sides: ( a + b )( a – b ) = b(a – b ) Divide both sides by ( …

Indicate and explain the logical error in the following set of algebraic expressions Let a=b square both sides to get a^2=b^2 a^2=b*b Since a=b, then a^2=a*b Subtract b^2 from both sides a^2-b^2=a*b-b^2 Factor both sides: (a+b)(a-b)=b(a-b) …

I have absolutely no idea how to factor the following: b² + 4b = 4b² I think you subtract 4b² from both sides: 3b² + 4b = 0 Then b(3b + 4) = 0 Then b = 0 and b = -4/3 Is this correct?
