4x1042x103400x105 12x106 in engineering notation Calcuator

(4x104)/(2x10-3+400x10-5) + 1/(2x10-6) in engineering notation. Calcuator order of operations practice. Try to punch this in a single sequence.

Solution

(4x10⁴)/(2x10^-3+400x10^-5) + 1/(2x10^-6)

=(4x10⁴)/(2x10^-3+4x10²x10^-5) + 1/(2x10^-6)

=(4x10⁴)/(2x10^-3 +4x10^-3) + 1/(2x10^-6)

=(4x10⁴)/(6x10^-3) + 1/(2x10^-6)

=((4/6)x10⁴⁺³) + ((1/2)x10⁶)

=((2/3)x10⁷) + ((1/2)x10⁶)

=((20/3)x10⁶) + ((1/2)x10⁶)

=((20/3)+(1/2))x10⁶

=(43/6)x10⁶

=7.167x10⁶
