To solve the problem while observing significant figure rules, let's carefully analyze the given calculation:### Problem:We are tasked with calculating
and determining the result in terms of significant figures.---### Step 1: Perform the multiplication
---### Step 2: Determine the number of significant figures in each value-
: This has **2 significant figures**.-
: This has **1 significant figure** (the leading zero is not significant).---### Step 3: Apply the rule for significant figures in multiplicationWhen multiplying or dividing, the result should have the same number of significant figures as the factor with the **fewest significant figures**. In this case,
has only **1 significant figure**, so the result must also be rounded to **1 significant figure**.---### Step 4: Round the resultThe unrounded result is
. Rounding this to **1 significant figure** gives:
---### Final Answer:
