How to find the difference between scientific notations #1 times 10^-49# and #2 times 10^-50#?

Answer 1

Avery Alexander

#8×10^(−50)#

#1×10^(−49)# can be written as #10×10^(−50)#

Hence, difference between #1×10^(−49)# and #2×10^(−50)# is #8×10^(−50)#

To find the difference between 1 × 10^-49 and 2 × 10^-50, you need to first convert them to the same exponent.

1 × 10^-49 is equivalent to 0.1 × 10^-48, and 2 × 10^-50 is equivalent to 0.2 × 10^-49.

The difference between the two is 0.1 × 10^-48.

To find the difference between scientific notations (1 \times 10^{-49}) and (2 \times 10^{-50}), subtract the exponents while keeping the base (10) unchanged. So, (1 \times 10^{-49} - 2 \times 10^{-50}) equals (1 \times 10^{-49} - 0.2 \times 10^{-49}), which simplifies to (0.8 \times 10^{-49}). Therefore, the difference between the two notations is (0.8 \times 10^{-49}).

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
